The Oderské vrchy, in English the Oder Mountains or, less commonly, Odra Highlands is a mountain range in the Czech Republic which forms the Eastern Sudetes (part of the Sudetes Mountain Range) and the eastern rim of the larger Bohemian Massif. The Moravian Gate separates it from the Western Carpathians in the southeast. The highest peak is Fidlův kopec at a height of 680 metres (2,230 ft). In the Oderské vrchy is the source of the Oder river, the second longest river in Poland.
The range is located entirely in Czech territory and create a slight highland within the Eastern Sudetes mountains, frequently stated to be part of the larger Nízký Jeseník mountainous region stretching up to the Hrubý Jeseník range and the Opawskie Mountains in the northwest. To the southeast, Oderské vrchy borders the Moravian Gate, to the south and west, it borders the basin of the Bečva river and the Haná lowlands, while in the north, the range ends near Ostrava and Opava in Czech Silesia. Other cities surrounding the mountains include Olomouc in the southwest, as well as Odry and Bílovec.
Large parts of the mountains are part of the Libavá military training area. Though recently reduced in size, this area, except for the trails to the source of the Oder river, is not open to tourists or visitors.
